(a) SEM images of biofilms formed by P. aeruginosa PAO1 after incubation with different concentrations of CS and CSCE for 24 h at 37 °C in a shaking incubator. (b) Plot of the in vivo evaluation of the antibacterial effects of the CSCE nanocomposites. The abdomen-infected mice were i.p. administrated with PBS, CE, CS, CSCE at 6, 12, and 24 h after the establishment of P. aeruginosa PAO1 in the mouse abdomen. (c) The number of dead mice in these groups.
